“There is a vast difference between what you can get from the mind and what you can get from the heart. The mind is limited; the heart is unlimited.”
When it comes to the heart a lot of things are involved, like it direct us on what to do right or wrong, its that soft part of you that allows anything go with out over thinking it.
There are so much things the heart does, affects us in different ways, so say "i just wana kill my self cause its not worth it"! buh have you got God in your heart? Do we allow our heart make 100% decision for Us?
Of course there is so much about the heart, i want you to ask your self, how does my heart feel(light or heavy), full of emotions? buh remember, you dont need anyone to make your heart lighter or joyful, you can do it all by your selves.
